1.	A pit 5 m long and 3.5 m wide is dug to a certain depth. If the volume of earth taken out of it is 14 m3, what is the depth of the pit?
Answer» We know that, Volume of cuboid = Length × Breadth × Height Let the depth of the pit be x m Therefore, Volume = 5 × 3.5 × x It is given in the question that, Volume = 14 m³ Therefore, Depth, x = \(\frac{Volume}{Length\,\times\,Width}\) x = \(\frac{14}{5\,\times\,3.5}\) = 0.8 m = 80 cm

A pit 5 m long and 3.5 m wide is dug to a certain depth. If the volume of earth taken out of it is 14 m3, what is the depth of the pit?

Answer»

We know that,

Volume of cuboid = Length × Breadth × Height

Let the depth of the pit be x m

Therefore,

Volume = 5 × 3.5 × x

It is given in the question that,

Volume = 14 m³

Therefore,

Depth, x = \(\frac{Volume}{Length\,\times\,Width}\)

x = \(\frac{14}{5\,\times\,3.5}\)

= 0.8 m

= 80 cm
